CVE-2024-54677Network attack vector

Server crash via unbounded example uploads

Published Dec 17, 2024 · Updated Nov 3, 2025

Uncontrolled resource consumption in Apache Tomcat's examples web application allows remote attackers to crash the server through uploads. The affected upload examples read request data without size limits until heap exhaustion raises an OutOfMemoryError. Exploitation requires the bundled examples application to remain deployed and reachable; the failure interrupts the entire Tomcat process.
